Question
The time period of sound is increased by 4 times. Find the ratio of the new speed to the old speed.
Answer: Option A
:
A
Speed of sound in a medium is a characteristic of the medium and temperature.
v∝√T√ρM
where:
v: Speed of sound
T: Temperature
ρ: Density
M: Molecular Mass of the medium
Increasing time period decreases the frequency of the wave.
v=fλ still holds because wavelength increases to maintain the speed of the wave in the medium.
